Debit my account without my consent

<p>Good day </p> <p> </p> <p>I have been a loyal customer of Cell C for over three years. I have paid my contract up and migrated to prepaid. However seems like they just cant get enough of my account.To my suprise R 400 odd has been debited from my cheque account Monday night. I mean now really no one told me that they will continue debiting my account if i paid up my contract. This is unaceptable serivce really i cant take this i want this debit order reversed back into my account before the end of this week. I will be closing my account soon so before i close my bank account credit my account.</p> <p> </p> <p>I dont want an automated response i actually want someone to call me or send me a detailed email with the statement as to why you debited my account.</p> <p> </p> <p>Waiting upon your response.</p> <p> </p> <p> </p>
